Since turning on this instance, email going out under the feddit.online domain has been a nightmare experience.
- iCloud won't accept the email what-so-ever. Just refuses to talk to the email server.
- Gmail gives it a 0 spam score (perfectly ok)
- ProtonMail says it's OK
- Runbox.com sends it to the spam folder
- Hover.com says it is mildly spam likely
- An email provider in NZ gave it a super high spam score
This means that every email provider pulls the rules out of their butts, clearly not using any data, or else there would be a much closer consensus.
A common claim from those that called it spam, or likely spam, is that the .online TLD is likely spam. This is crazy. Most of my spam comes from .com domains, which they say are fine.
iCloud was the dealbreaker.
Going forward, all email will come from feddit-online-email.com. I don't know how icloud will handle it, but since it is being accepted more by the other email providers I've tried, I'm hopeful. I'm still using my own email server, hoping this isn't a problem for iCloud.
If you have an icloud email address , can you try opening a private browser window and running this URL and telling me if you get the email? https://feddit.online/test_email?email [enter your email address here>]
